SPECIFICATION forming part of Letters Patent No. 752,062, dated February 16, 1904.

To all whom, it may concern: I

I Be it known that 1, JAMES EDWIN GI BS, a citizen of the United States,resi ding at Bridgewater, in the county of Rockingham and State of Virginia, have invented a new and useful. Sash-Fastener, of which the following is a specification. V

This invention relates to sash-fasteners, and is designedto provide an improved device of this character which is arranged to mutually interlock the upper and lower sashes and also secure the same to the window frame or casing, whereby the sashes may be effectually locked when in closed position and also looked in different open positions, so as to secure ventilation at the top and bottom of the window and also to'have the fastener located so as to go inaccessible from the exterior of the win- It is furthermore designed to arrange the locking-bolts so that one of them aotuates the other and also forms a guard to hold the same in place, thereby to secure an efiective and simultaneous operation of the bolt.

Another object is to provide for actuating the fastening when at a considerable elevation without requiring the operator to stand upon a chair or the window-sill to reach the fastening device.

Withthese' and other objects in view the present invention consists in the combination after more fully. described, shown in the accompanying drawings, and particularly pointed. out in the'appended claims, it being understood that changes in theform, proportion, size, and minor details may be made within the scope of the claims without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure 1 is a perspective view showing adjacent portion of upper and tener applied thereto to lock the sashes in open position. Fig.2 is a horizontal sectional view taken across the top of the lower sash with the top plate of the sash-fastener casing removed. Fig. 3 is a cross-sectional view on the line 3 3 of Fig. 2. Fig. t is a detail persemi No. 121,362. (No model.)

the window-casing. Fig. 5 is a detail perspective view of the bolt for mutually interlocking the sashes.

Like characters of reference designate corresponding parts in all of the figures of the drawings.

The working parts of the present form of sash-fastener are housed with a casing 1,whioh .is designed to besecured upon the top of the top rail of a lower sash 2 and at one end thereof, preferably the righthand end. That end of the casing which is next to the windowframe 3 is provided with a vertical seat or recess 4: to receive thesash-cord 5, and thereby to permit of the casing being set as close as possible to the frame 3. Withinthe casing there is an endwise-reciprocatorjr bolt 6, which is adapted to be projected through one end of thecasing and entered into one of a'series of sockets or seats formed in the window-frame, thereby to lock the sash 2. The bolt 6 is slidable in a guideway formed by the front of the-casingand a longitudinal upstandingrib or flange 7, which rises from the bottom of the casing and terminates short of the front end of the latter. The rear end portion of the bolt is provided in its upper-face with a seat or recess 8,-and between the latter and the front end of the boltthe inner orrear' side thereof is laterally enlarged and inclined rearwardly, as at 9,130 form a cam-surface, and the under side of the bolt beneath the camsurface is cut away or recessed, as at 10, for

the reception of thereducedinner end of a bolt 11, which is disposed at substantially right angles to the bolt 9 and projects through the backof the casing toenter one of the series of seats or sockets in the adjacent side rail of the upper sash 12, thereby to mutually interlock the sashes. A stud or projection 13 rises from an intermediate part of the rear cut-away end portion of the bolt 11 and is disposed in frictional engagement with the inclined or cam face 9 of the bolt 6, whereby a forward movement of the latter imparts a forward movement to the bolt 11. It will here be observed that the inner reducedportion of the bolt 11 works beneath the bolt 6, and hence the latter forms a guard to prevent tilting or displacement of the bolt 11. A suitable guideway is formed for the bolt 11 by means of a pair of ribs or flanges 14, which rise from the bottom of the casing and are disposed transversely thereof. For operating the bolt there is provided a bell-crank or angle-lever 15, which is pivotally mounted upon a stud or post 16, rising from the bottom of the casing in rear of the transverse bolt 11. Theinner arm 17 of the lever has its free end working between the stud or projection 13 and the shoulder formed by the reduced por-' tion of the bolt 11, while the arm 18 is seated in the recess 8 of the bolt 6 and is also projected through a longitudinal slot 19 in the front of the casing, whereby the outer end of the arm 18 is accessible for manipulation. It will now be understood that when the outer free end of the lever is swung forwardly it will carry the main bolt 6 forwardly into engagement with the window-frame, and at the same time the cam-surface 9 of the bolt working against the stud 13 of the bolt 11 forces the latter outwardly and into engagement with the upper sash. It is preferred to have the bolts normally held at their outer limits, and this is accomplished by means of a coiled spring 20, encircling the stud or post 16, with one end portion,

21, bearing against the back of the casing and v.

the other end, 22, connected to the arm 18 of the lever, whereby the bolts are yieldably held at their forward limits and may be retracted by swinging the lever rearwardly. It Will here be noted that the lever operates the bolt 6 and the latter in turn operates the bolt 11; but the latter is retracted by the arm 17 of the lever. For convenience in manipulating the lever when the lower sash is in an elevated position there is provided an upstanding angle or bellcrank lever 23, which is fulcrumed, as at 24, upon a pendent extension 25 of the outer side of the casing, with the upstanding arm of the lever lying in frictional engagement with the front side of the arm 18, there being a suitable cord, wire, or the like 26 connected to the other arm of the lever, with its lower end in'position to be conveniently reached by the operator when standing on the floor. The extension 25 also forms a bracket or attachingplate, which is secured to the front side of the upper rail of the lower sash by means of suitable fastenings set through the bracket.

What I claim is 1. A lock comprising a casing having angularly-related guides, a pair of bolts arranged in the guides and extending through one wall and terminating short of the other, one of the bolts being reduced and provided with a stud arranged at the reduced portion and forming a seat, and the other bolt being provided with a lateral enlargement having a cam edge to engage the stud and forming a guard and arranged over the bolt having the stud, an approximately L-shaped lever disposed horizontally and having one arm arranged in the said seat and having its other arm engaging the bolt having the cam, and extended beyond the casing, and a bell-crank lever disposed externally of the casing and operating in a plane parallel with the front face of the sash and arranged at substantially right angles to the L-shaped lever and directly engaging the same.

2. A look embodying a casing, a bolt therein, an interiorly arranged lever connected with the bolt and projected externally of the casing, and a lever disposed externally of the casing and operating in a plane parallel with the front face of the sash and arranged at substantially right angles to the first-mentioned lever and directly engaging the same, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

JAMES EDWIN GIBBS.
